A new clade, based on partial LSU rDNA sequences, of unarmoured dinoflagellates.
The order Gymnodiniales comprises unarmoured dinoflagellates. However, the lack of sequences hindered determining the phylogenetic positions and systematic relationships of several gymnodinioid taxa. In this study, a monophyletic clade was defined for the species Ceratoperidinium margalefii Loeblich III, Gyrodinium falcatum Kofoid & Swezy, three Cochlodinium species, and two Gymnodinium-like di...
متن کاملPHYLOGENY OF DINOFLAGELLATES BASED ON MITOCHONDRIAL CYTOCHROME b AND NUCLEAR SMALL SUBUNIT rDNA SEQUENCE COMPARISONS
Despite their evolutionary and ecological importance, dinoflagellate phylogeny remains poorly resolved. Here we explored the utility of mitochondrial cytochrome b (cob) in inferring a dinoflagellate tree and focused on resolving the relationship between fucoxanthin-and peridinin-containing taxa. Trees were inferred using cob and small subunit rDNA alone or in combination as concatenated data an...
متن کاملPhylogeny of the Peronosporomycetes ( Oomycota ) based on partial sequences of the large ribosomal subunit ( LSU rDNA )
The phylogeny of the nuclear large ribosomal subunit (LSU) rDNA from Peronosporomycetes (Oomycota) was studied. Five orders Rhipidiales, Leptomitales, Saprolegniales, Pythiales and Peronosporales were included in the study in order to reveal phylogenetic relationships within the group. Based on maximum parsimony, neighbour-joining and maximum-likelihood the Peronosporomycetes seem to have evolv...
متن کاملon semihypergroups and hypergroups
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
